Add the ports to which the Web server listens.Direct Server InteractionDirect access to real servers can be provided in the following ways: Using Direct Server Return Using Direct Access Mode Assigning Multiple IP Addresses Using Proxy IP Addresses Mapping Ports Monitoring Real ServersUsing Direct Server ReturnSome clients may need direct access to the real servers (for example, to monitor a real serverfrom a management workstation). The Direct Server Return (DSR) feature allows the server torespond directly to the client. This capability is useful for sites where large amounts of data areflowing from servers to clients, such as with content providers or portal sites that typicallyhave asymmetric traffic patterns.DSR and content-intelligent Layer 7 switching cannot be performed at the same time becausecontent intelligent switching requires that all frames go back to the switch for connection splic-ing.N OTE – DSR requires that the server be set up to receive frames that have a destination IPaddress that is equal to the virtual server IP address.>> # /cfg/slb/virt 1/service 80/rport 0>> # /cfg/slb/real 1/addport 8001 (Add port 8001 to real server 1)>> # addport 8002 (Add port 8002 to real server 1)>> # ../real 2/addport 8001 (Add port 8001 to real server 2)>> # addport 8002 (Add port 8002 to real server 2)>> # ../real 3/addport 8001 (Add port 8001 to real server 3)>> # addport 8002 (Add port 8002 to real server 3)>> # ../real 4/addport 8001 (Add port 8001 to real server 4)>> # addport 8002 (Add port 8002 to real server 4)
